  1. Wiper/washers system check

    -1. Turn the windshield wiper switch to the OFF position, check the parameter(s) below with the HDS.

    Signal Threshold Current conditions
    Values Unit Values Unit
    Windshield Wiper Switch (LOW) OFF      
    Windshield Wiper Switch (HIGH) OFF      
    Windshield Wiper Switch (INT) OFF      
    Windshield Wiper Switch (LOW) OFF      

    Are all data list values correct?

    YES 

    Go to step 4.

    NO 

    Go to step 2.

  2. Determine possible failure area (windshield wiper/washer switch, others)

    -1. Turn the vehicle to the OFF (LOCK) mode.

    -2. Disconnect the following connector.

    Windshield wiper/washer switch 10P connector

    -3. Check the parameter(s) below with the HDS.

    Has the data list value changed from ON to OFF?

    YES 

    Replace the windshield wiper/washer switch .

    NO 

    Go to step 3.

  3. Shorted wire check (FR_WIPER_INT_SW, FR_WIPER_HI_SW, FR_WIPER_MIST_SW lines)

    -1. Turn the vehicle to the OFF (LOCK) mode.

    -2. Disconnect the following connector.

    Body control module connector D (40P) Body control module connector E (24P)

    -3. Measure the resistance between test points 1 and 2.

    Test condition Vehicle OFF (LOCK) mode
    Windshield wiper/washer switch 10P connector: disconnected
    Body control module connector D (40P): disconnected
    Test point 1 Body control module connector D (40P) No. 2

    Test point 2 Body ground
    Test point 1 Body control module connector D (40P) No. 4
    Test point 2 Body ground

    Is there 1.0 MΩ or more?

    YES 

    The FR_WIPER_INT_SW, FR_WIPER_HI_SW, and FR_WIPER_MIST_SW wires are OK. Faulty body control module; replace the body control module .

    NO 

    Repair a short to ground in the wire.

  4. Shorted wire check (FR_WIPER_MIST_SW to FR_WIPER_HI_SW, FR_WIPER_HI_SW to FR_WIPER_INT_SW, FR_WIPER_MIST_SW to FR_WIPER_INT_SW lines)

    -1. Check the parameter(s) below with the HDS.
